ANS-C01 Network Design Practice Question
A company wants to use Amazon Route 53 to resolve DNS queries for a domain they own. They want to ensure that DNS queries are answered quickly and that there is no single point of failure. Which configuration should they use?
⚠ Common exam trap
Candidates often think Route 53 is a regional service like EC2 or RDS, leading them to choose Option A, or they may mistakenly believe that creating multiple hosted zones or accounts increases redundancy, when in fact a single hosted zone with its four automatically assigned name servers already provides full fault tolerance and low latency.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a hosted zone and let Route 53 automatically handle the DNS resolution.
When you create a hosted zone in Route 53, AWS automatically provisions four authoritative name servers (NS records) distributed across multiple globally redundant data centers. This design inherently provides high availability and low-latency DNS resolution without any additional configuration, as Route 53 uses Anycast routing to direct queries to the nearest healthy name server.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy Route 53 in multiple AWS Regions.
Why it's wrong here
Route 53 is a global service, not regional.
- ✓
Create a hosted zone and let Route 53 automatically handle the DNS resolution.
Why this is correct
Route 53 is inherently highly available.
- ✗
Create multiple hosted zones in separate AWS accounts.
Why it's wrong here
Unnecessary complexity.
- ✗
Create a single hosted zone and assign it to one Route 53 name server.
Why it's wrong here
Route 53 automatically assigns four name servers for high availability.
